Standard Genetic Code
... instructions are used by translating the code into protein. The code of DNA/RNA nucleotides come in sets of three bases called a codon. Most of these codons are translated to an amino acid, but a few of the codons signal for the ribosome to let go of the growing protein, thus stopping translation. A ...
